Hangouts was one of many Google apps that received pretty significant updates last week. Version 1.2 finally brought availability statuses for people on your contact list, better organization of contacts, and several other improvements. Under-the-hood, however, I spotted a few more additions that don't seem to be live just yet, which is exactly what we have APK teardowns around here for.

Hey, you. Yes, you. Don't forget to check out the Gmail teardown I did on Saturday and voice your opinion on ads that are coming to the Android app.

Carbon, one of the most hotly anticipated Twitter clients to ever come to Android, got an update today to version 1.2, bringing with it a ton of useful enhancements.

First among these is the ability to browse from links or watch YouTube videos in the app, saving time that would otherwise be spent leaving the app to see content somewhere else.

The update also adds Vine preview/playback, people search, a new image viewer, the ability to save images, optional style tweaks (like changing tweet font size), and the ability to change notification frequency, among other things.

Press, arguably the most well-designed Reader client of them all, got a sizeable update today. It's the "biggest update yet," in fact. Climbing up to version number 1.2, Press got some useful new features. Though this update isn't the one with which Press migrates to "a new backend syncing solution" as it is promised to do once Reader takes its final breath, it's definitely an update worth looking at.

The Barnes & Noble NOOK Color has been the e-reader of choice for many Android power users because of its hackability, making it easy to transform it into a full featured tablet. B&N must've taken note from the Android dev community, because an update has just been released for the NOOK Color that brings Froyo, apps, flash player, and more to this budget friendly device.
